After clicking on the "Manual Entry" button, you'll be taken a page similar to the one shown below.
Select Date (Red): You'd select the date that you'd like to apply these payroll changes to.
Select Branch (Blue): If you're company has multiple branches, you can easily swap between the different branches, as needed.

Hours, Miles, Commission, Bonus, Per Diem, Tips, Deductions(-) (Gold): This field is where you're able to update employees' hours, as well as other bonuses to their payroll for the selected date.
